Triskelion

A triskelion or triskele is a motif consisting of a triple spiral exhibiting rotational symmetry. The spiral design can be based on interlocking Archimedean spirals, or represent three bent human legs.

Both terms are from Greek "τρισκέλιον" (triskelion) or "τρισκελής" (triskeles), "three-legged", from prefix "τρι-" (tri-), "three times" + "σκέλος" (skelos), "leg".

A triskelion is a traditional symbol of Sicily, where it is called trinacria, and of the Isle of Man.

The triskelion symbol appears in many early cultures, the first in Malta (4400–3600 BC) and in the astronomical calendar at the famous megalithic tomb of Newgrange in Ireland built around 3200 BC,Mycenaean vessels, on coinage in Lycia, and on staters of Pamphylia (at Aspendos, 370–333 BC) and Pisidia. It appears as a heraldic emblem on warriors' shields depicted on Greek pottery.

The triskelion is an ancient symbol of Sicily, with the head of the Gorgon, whose hair are snakes, from which radiate three legs bent at the knee. The symbol dates back to when Sicily was part of Magna Graecia, the colonial extension of Greece beyond the Aegean.Pliny the Elder attributes the origin of the triskelion of Sicily to the triangular form of the island, the ancient Trinacria (from the Greek tri- (three) and akra (end, limb)), which consists of three large capes equidistant from each other, pointing in their respective directions, the names of which were Pelorus, Pachynus, and Lilybæum.
